Representatives of the title compounds are converted into 4-alkoxycarbonyl-4-hydroxy-3-methylceph-2-em 1,1-dioxides by the action of palladium–charcoal in ethyl acetate; an X-ray analysis of one of the products reveals that the 4-hydroxy function is α-oriented.
通过钯-木炭在乙酸乙酯中的作用,将标题化合物的代表转化为4-烷氧基羰基-4-羟基-3-甲基Ceph-2-em 1,1-二氧化物。对一种产物的X射线分析表明4-羟基官能团是α-定向的。
